Safety information · MOTS-c · Updated Aug 29, 2026
MOTS-c is a mitochondrial-derived peptide, meaning it is encoded by mitochondrial DNA and produced naturally within the body's own mitochondria. Researchers have studied its role in metabolic regulation, insulin sensitivity, and cellular energy, largely in preclinical and animal models.
At Belle, MOTS-c is offered in compounded injectable form, prescribed when deemed clinically appropriate by a licensed healthcare provider. Please review the following important safety information before beginning treatment.
What Is MOTS-c?
MOTS-c therapy is considered an elective wellness treatment. Compounded MOTS-c is not approved by the FDA for any indication, and it has not been evaluated by the FDA for energy, metabolic health, athletic performance, or anti-aging purposes. It is not intended to diagnose, treat, cure, or prevent any disease.
Human research on MOTS-c is early. Well-controlled clinical trials in people are limited, and the long-term safety of supplemental MOTS-c has not been established. Your provider can help you weigh what is known against what is not.
Always consult your healthcare provider before beginning any injectable regimen, especially if you have pre-existing health conditions.

Are under 18 years of age
Have uncontrolled chronic illness without supervision from a licensed provider
